Reliability analysis of wind-excited structures

In plane shear and bending for first gradient inextensible pantographic sheets: numerical study of deformed shapes and global constraint reactions

“…Further developments entail the introduction of (i) non straight fibers prior to deformation (see, e.g., [51] for the model with extensible fibers), (ii) sliding between fibers or problems concerning impact and impulsive loading (see, for more detail, [52][53][54]), and (iii) nonlinear constitutive behavior accounting for a micropolar anisotropy induced by the fibers [55,56]. Other issues of relevance in the structural context are related to damage and fracture characterization (see for some examples [57][58][59][60][61][62]) and fluid-structure interaction, which is particularly delicate for these kinds of light systems and with heterogeneous material properties (see for further details [63][64][65][66]). These aspects can involve instability of the structure, which being very complex require unconventional computational methods (see, e.g., [67][68][69][70]).…”

Gedanken experiments for the determination of two-dimensional linear second gradient elasticity coefficients

“…The deficiencies of classical approaches when the material behavior exhibits size-scale effects are investigated in [59], and in [47] a novel invariance requirement (micro-randomness) in addition to isotropy is formulated, which implies conformal invariance of the curvature. The numerical investigation of structures of the type considered also requires special attention, and it is therefore important in the development of novel techniques [5][6][7][8][9]37,38,[48][49][50][51]65] or the proper employment of the existing ones (see, for instance, [68], where Galerkin boundary element method is used to address a class of strain gradient elastic materials).…”

An efficient framework for the elasto-plastic reliability assessment of uncertain wind excited systems

“…It is also the basis on which state-of-theart performance-based design is founded [5,6]. Recently there has been significant interest in developing specific reliabilitybased procedures for assessing the performance of wind excited structures [7][8][9][10][11][12][13][14][15][16][17]. However, as in classic reliability analysis, the limit states indicating structural failure are associated with first yield of the structural system.…”
